((1154-2 Thisinvention relates to a method of manufacturing corn plasters and otherlike articles. The object of'the invention is to provide an improvedmethod by which thesearticles may be 5 rapidly manufactured in quantity;the method employed resulting in an improved product so manufacturedthat the sanitary characteristics desirable in an article of this kindare fully preserved. 7

Specifically, the inventioncontemplates the feeding of a strip or web oftextile materialcoated on one of its faces with an adhesive or stickysubstance and provided on its opposite face with a soft cushion materialor pad; the

1 perforating of this strip or web, the perforations formed thereincomprising the central openings appearing in the eventually-formed cornplas-p ters; the uniting of a strip or web of a thin textile fabricbacking with the first strip by adhesively uniting it with the soft backof the first strip, then dieing out the plasters from the compositestrip, and adhesively attaching the plasfinishedplasters; Fig. 4 is aview of the opposite face of the plaster; Fig. 5 is a sectional view onthe line 5-5 of Fig. 3, looking in the direction of the arrows; Fig. 6is a plan view of a number of the plasters mounted on the foraminousbacking materiahFig. '7 is a'sectional'view through a part of the stripshown in Fig. 2; and Fig. 8 is a sectional view through the dies forstamping the perforations in the strip shown in Fig. 2.

The corn plaster manufactured in accordance with my improved process andshown in its finished state in Figs. 3 to 5, consists primarily of twomain portions or layers; one portion consive or sticky face 2 which isplaced in contact with the toe and which adhesively holds the plaster inplace. The other portion of the plas- 5 ter consists of a backing of athin cotton fabric manufacture of the in it; Fig.3 is a view of'thefront face of one of the stitutes the body of the plaster and consistsof a ring shaped pad or annulus 1 having an adhe- 3 which is adhesivelyattached to the back of the ring shaped portion 1 so that it covers thecorn positioned within the central opening 'of the ring 1 when theplaster is Worn. 'These plasters may be made in any shape to suitdifferent re-, "5! I .quirements, theconventionaloval shape being hereinshown for convenience." When sold, the plasters are mounted forprotective purposes upon a strip or sheetof'an open-mesh textile fabricsuch as 'crinoline, on'which they are heldby the adhesive material 2:This. backing 2 0 is impregnated .with a suitable substance whichpermits the plaster tobe easily stripped from it when the'plaster isready'for applica tion over the corn of 'the user,

' In Carrying-outthe process of the invention, I; utilize a main stripor web 1a, from which the part 1 of the corn plaster is made. i Thisstrip is fed from a roll 11 by any suitable feeding means and passesunder a roller 12 and between dies 13, r and 14 which produce theregularlyspaced open ings or holes 15in the strip, these openings or 7holes constitutingthose formed in the center of the body portion 1 ofthe finished plaster. The

strip 1a iscomposed of a textile fabric having a 255 soft pad-likeback17 and its opposite face, shown uppermost in Fig. 1, coated with theadhesive orsticky material 2. As strip or Web 1a is fed between'the dies13 and 14 which form the holes 15, the disk material '21 punched out ofthese holes is carried away or otherwise disposed of in any suitablemanner, as for instance, by being forced up through the hollow male die13 by the action of a stud 18 located in the female die.

14, as shown in Fig. 8. Any other means for re- 5 moving this wastematerial 21 may be used'. I When the perforated web 1a leaves the dies'13 r and 14, it is .moved betweenrollers 22 and 23 in company with aweb 3a fed'from a roll135' and of the thin textile fabric which formsthe back-l ing 3 of the completed plaster. The web-.3d'has a sticky oradhesive face 24 which may be medicated if desired, and which,whenbrought in contact with the soft back 17 of the web 1a by the pressureof the'rollers 22 and 23, causes the two strips 1a and 3a, to beadhesively united. The composite strip, consisting of the two layers j1a and 3a is now fed between dies 25 and 26 which operate on the dottedlines in Fig. 2 to 5 punch out the plasters. The male die 25 forces theplasters shown at 27 in Fig. 1 out of the strip, its upward movementbringing the plasters against the face of a strip 20 of open-mesh fabricor other foraminous material, fed from a roll 28,

As the strip 20 moves away from the dies 26' and 27, hearing. theplasters on its under face,

the plasters so carried are brought across the face of a heated plate31, which softensthe adhesive located between the face 24 of the fabricbacking 3 and the back 17 of the strip 10 so that a very secure adhesionbetween'the fabric back ing 3 and the body portion 1 of each .of theplasters results. The plate 31 is maintained at such a temperature asnot to materially affect the adhesive face 2 of the plasters sothat nodifficulty is had by the user of the plasters in stripping'them bodilyfrom their backing strip 20 when he desires to use them.

Thestrip 20 carryingthe plasters 2'7v is neXt carried between knifemembers 32, which sever the strip into lengths, eachlength carrying therequired number of plasters, these lengths being then ready for packing.

While the heating plate 31 is shown as positioned between the dies 25and26 and the cutters without departing from the spirit of this vention." lp What I claim'is: v I i l. The" process of making corn plasters and thelike, consisting in feeding a composite web of fabric, one of the layersof the web being pr'o vided with spaced perforations and-having anexposed sticky surface, in stamping corn plasters from the composite webwith 'a -die and forcing them out of the web by the die and'pressingthem against a web of open-mesh'textile fabric by the die to adhesivelyattach them thereto, in moving the plasters over a heated surface whilecarried on the web of open-mesh textile fabric and in cutting the fabricinto sections I 2. The process of making corn plasters and the likeconsisting in feeding a web composed of a pad-like material providedwith a stick surface, perforating the web and forcing waste-material'out of the perforations'simultaneously with the perforating operation,adhesively uniting a textile fabric backing to the back of theperforated web to thus form a composite web, punching out plasters fromthe composite web and forcing said plasters away from the web by thepunching operation, feeding a web of foraminous fabric adjacent to thecomposite web so that the punchedout plasters are directed against saidforaminous fabric when said plastersare punched out of the compositeweb, carryingthe backs of the plasters against a heated member whilesaid plasters are attached to the foraminous fabric, and severing theforaminous fabric into lengths.

3. The process of making corn plasters consisting in feeding severalfabric webs, at least one of -which is provided with a sticky face,perforating the sticky-faced web and adhesively uniting it with at leasta second web, punching corn plasters from the webs thus united and.simultaneously forcing the corn plasters out of the united webs and intocontact with a fabric backing to adhesivelyattach them theret and bring:ing the fabric backing plasters adhering thereto over a heated elementto intimately bond the plasters to the backing. g

'4. In the process of making corn plastersthe steps of stamping outplasters from a fabric web and forcing the plasters out of and away fromthe web by the stamping operation and bringing them into contact with afabric backing to stick them thereon, and in bringing the plasters andfabric backing into contact with a heated element to bond the'plastersto the backing.

5. The process of making corn plasters consisting. in feeding severalfabric webs, at least one of which is'ip'rovided with a stickyface,perforating the sticky faced webandadhesively uniting itlwith at least asecond web, punching corn plasters from the webs thus united and simultan'eously forcing the corn plasters out of the united webs and intocontact with the fabric backing to adhesively attach them thereto, andbringing the fabric backing and plasters adhering thereto across aheated element'with the fabricbacking remotely disposed from the elementto thereby bond the :plasterwebs.

6. The process of making corn plasters'consisting in feeding several"fabric webs, at, least one of which is provided witha, sticky face,perforating the'sticky faced web and adhesivelyuniting it with at leasta second web, punching corn plasters from the webs thus united andsimultaneously forcing the corn plasters out of the united 'webs andinto contact with the fabric backing to adhesively attach them thereto,and bringing the fabric backing and plasters adhering thereto across aheatedelement; the element being located to applya more intensive heatto the contacting facesof' the plaster webs'than. the contacting facesof the fabric-backing and the touching pl etenweb.
